Happy new year!

• Fix: Correctly pass processing classpath to kapt.
• Fix: Clear KSP2's KSPCoreEnvironment as it leaks memory across multiple runs in tests.
• Fix: Clear KSP2's KspApplicationManager as an addition to the above, as an extra defensive measure.

Special thanks to @​TheMrMilchmann for contributing to this release!
